The correct answer is:
D. volcanic eruptions
Explanation:
4.0 Billion Years Ago, Earth’s outside cools enough for most of the water that has accumulated in the atmosphere from comets and volcanic outgassing to rain down to the surface and fill in the basins making the world’s oceans. Explosive volcanic eruptions change the global climate largely through including sulfur, improve the salinity near the Greenland Sea, and considerably reduces static balance, which means more surface water sinks into the deep ocean.
b. Lipids
c. Carbohydrates
d. Protein
The Nutrients that contains the most calories per gram are lipids (or fats), with 9 calories per gram compared to 4 calories per gram in both protein and carbohydrates.
Your question asks which one of the following nutrients that contains the most calories per gram.
The answer is lipids (or fats).
When we look at calories per gram, which is a measure of energy density, lipids contain more calories per gram than protein and carbohydrates.
In fact, lipids contain 9 calories per gram, while protein and carbohydrates each contain 4 calories per gram.
Vitamins do not contribute calories, but they are essential for various bodily functions.
This is why fatty foods are considered calorie-dense, meaning they have more calories per unit mass than other nutrients.
For example, animals tend to seek lipid-rich food for their higher energy content due to the high caloric content.

The correct option is (b) Lipids.
Further Explanation:
Certain molecules or polymers are present in all the living organisms those molecules are known as biomolecules that include protein, carbohydrate, and fats. These different molecules provide a differential amount of energy to the living system.
Proteins- are the polymers that are made up of amino acids. Amino acids are linked to each other through peptide molecules.
Carbohydrate- they are the polymers that are made up of monosaccharide to further form disaccharide and polysaccharide. The bonds present between the sugar units in the carbohydrate molecules are known as the glycosidic bond.
Lipids- they contain long chains of fatty acids. It provides high energy or calorie per gram.
Vitamin- they are just the organic molecules that are required in low quantity by the organism to sustain life. It includes vitamin b, a, d, c, k, etc.

Anna's dog's weight falling outside the average range doesn't necessarily indicate the source is unreliable as it could be affected by individual variability. A broader sample would need to be assessed. Fur color, unrelated to weight, is determined by genotypes.
Anna's female Labrador Retriever being 38 kg (or 83 lb) falls outside the average weight reported in the encyclopedia for female Labradors, which is 25-32 kg (or 55-70 lb). However, these weights are averages and there can be exceptions due to factors such as individual genetics, diet and physical activity level. But, if a large number of Labrador Retrievers greatly exceed or fall below these averages, then it could indicate a problem with the reliability of the source. It's also important to cross-verify such information with other reliable sources. Meanwhile, the fur color is not associated with the weight, but based on alleles. For example, the ee_ genotype makes a Labrador yellow and B_E_ genotype turns it black.

Answer:
The major reservoir for Ammonia is the natural soil, where it is present in abundance.
Explanation:
In soil, ammonia is found in quite abundance, where it is changed into nitrate through a process commonly knows as Nitrification. In the nitrification process, first, nitrite is formed which is followed by its conversion into nitrate by a bacteria known as Nitrobacteria. Finally, this nitrate is consumed by the plants, which are then eaten up by the animals.
Ammonia is a crucial compound found variously within the biosphere. In animals, it is processed into safer compounds for excretion, while in the environment, it is both a product of decomposition processes and an important component for agricultural practices.
Ammonia is a nitrogenous compound that plays a significant role in various biological and ecological contexts. In terrestrial animals, the major reservoir for ammonia is the biological system where it is present in compounds such as proteins and nucleic acids. Through the process of metabolism, animals convert the toxic ammonia into urea or uric acid, which are safer for the organism. This is exemplified by the urea cycle in mammals and the corresponding processes in birds, reptiles, and terrestrial arthropods.
Additionally, ammonia is an important product of ammonification, a process that occurs during the decomposition of nitrogen-containing organic compounds. A small percentage of ammonia is also released into the atmosphere.
Furthermore, ammonia is crucial for our economy, particularly in the agriculture industry. It is heavily utilized in the production of fertilizers and also serves as a vital ingredient for the growth of several crops.

Answer:
Kingdom Plantae
Explanation:
All living organisms were classified into a large group called KINGDOM, based on the certain features or characteristics that they possessed. Organisms in Kingdom Plantae are multicellular eukaryotic organisms that are non-motile and usually found on substrate materials.
Organisms in this Kingdom are further divided into different divisions. The organism described to produce seeds and having a vascular system in this question belongs to a group under Kingdom Plantae called Angiosperms i.e. seed bearing plants.
All other divisions mentioned in the question do not produce seeds. Seed-bearing is peculiar to plants.
